Eaton N48M47B55EE Transformer - UL Listed, NEMA TP-1

K-Factor nonlinear design with electrostatically shielded construction reduces harmonic currents and minimizes stray voltage coupling. The business impact is improved power quality, lower transformer heating, and extended equipment life, which translates to fewer maintenance cycles in high-load manufacturing lines. This makes the N48M47B55EE well-suited for drives, presses, and mixed loads that create harmonic richness in industrial power distribution. Voltage flexibility and capacity: With a 500 kVA rating, 480 V primary, and 480Y/277 V secondary, this transformer supports critical loads from motors to lighting with tight regulation. The ±2.5% taps provide on-site voltage adjustment to compensate for panel drops, reducing voltage-related faults and unnecessary capacitor bank usage. In practice, this means fewer outages and improved uptime for heavy machinery. Cooling and construction: Aluminum coil and ventilated KT-13 design deliver robust thermal performance with an 80°C rise. The ventilated design reduces hotspot risk under peak loads, enabling longer service intervals and compliant operation in warm environments. The choice of aluminum supports lighter weight and easier handling during installation and retrofits. Compliance and service: UL Listed and NEMA TP-1 compliant, with NEMA TP-1 efficient catalog notes, provide regulatory assurance and energy savings. The product carries a one-year warranty (or 18 months from shipment) and Eaton's support network helps with field services and parts. Electrostatic shielding adds an extra layer of protection against EMI in sensitive facilities. Installation and integration: Designed for straightforward integration with standard distribution equipment and 480 V panels, with common 500 kVA footprint expectations and compatible with Eaton's Transformer Flex Center resources. The result is faster commissioning, reduced spare parts inventory, and a lower total cost of ownership for industrial facilities.
